INVESTIGATION AND REINFORCEMENT MEASURES OF SOFT SOIL SUBGRADE OF EXPRESSWAY
In order to ensure the construction level of expressways in soft soil areas,taking the Dongchuan Gele section of the Kunming Qiaojia expressway as an example,this paper studies the survey methods and reinforcement measures for soft soil roadbed of expressways.Using static penetration testing to investigate the geological conditions of the engineering section,and analyzing the geological survey results,a roadbed reinforcement plan is formulated based on the analysis results to ensure the stability of the soft soil roadbed,reduce roadbed settlement,and enhance the bearing capacity of the roadbed.After experimental analysis,it was found that the settlement results and bearing capacity of the roadbed after reinforcement are within the allowable standard range,meeting the construction standards.
